LPC85 Basically your bog standard orville LPC but ebony board,
57B was their top of the range Custom again ebony board, nibs 57 classic pups - only let down on those is this cheap plastic inlays, otherwise they're hard to fault. The Orville Joe Perry studio model also had an ebony board.

When they switched brands names to Epiphone in 1998 the Epi LPC90 model replaced the Orville LPC85 has an ebony board and are usually cheaper and easier to find so don't overlook them as they can go cheap just cos of the Epi logo. I picked up an LPC90 a little while back for under $200 on YJ and the quality of the MIJ EPi's easily matches the Orvilles I've had at a lot cheaper price. Epi also did a SG Gothic with an ebony board.

Got to say the ebony fujigen used on the ones I've had is very dark and smooth too. All mahogany bodies on the ebony boarded LPC's too .

Few days ago I missed a dead MINT ObG LPC with ebony board, nibs and all... and it was selling for exactly 1500€, here in EU.
I've been looking literally for ages for one like this and I missed it in front of my nose.
Bloody fool.
